Abstract

The invention belongs to the technical field of tunnel construction machinery, and mainly relates to a narrow-body double-cylinder concrete conveying pump adapted to a single track tunnel. The double-cylinder concrete conveying pump adapted to the single track tunnel has a frame (15); two concrete pumping oil cylinders (13) are arranged at the bottom of the frame (15) side by side; output ends of the two concrete pumping oil cylinders (13) both communicate with a hopper (4); a concrete conveying pipe (8) is arranged at the bottom of the frame (15); the front end of the concrete conveying pipe (8) communicates with the hopper (4), and the back end backwards extends out; a hydraulic system for supplying power to the whole concrete conveying pump is arranged above the frame (15); and telescopic support legs (6) are arranged at four corners of the frame (15). The double-cylinder concrete conveying pump adapted to the single track tunnel meets the requirements of pumping concrete by the single track tunnel, realizes the vehicle meeting in the tunnel, saves the construction cost, and guarantees the construction period requirements.

Description

technical field

[0001] The invention belongs to the technical field of tunnel construction machinery, and mainly relates to a double-cylinder concrete delivery pump suitable for single-track railway tunnels. Background technique

[0002] Tunnel support and lining is one of the key links in tunnel construction and the control link of tunnel forming quality. Both support and lining require concrete delivery pumps to transport the concrete transported by the concrete tank truck to the corresponding work area, and then professional equipment is used for support and lining operations. Concrete delivery pump is a professional operation equipment for concrete delivery. It has the advantages of large pumping capacity, high pumping efficiency and long pumping distance. Most of the tunnel construction uses double-cylinder 60 delivery pumps to meet the requirements of tunnel concrete delivery. In recent years, the railway construction in the western region has been rapid, and the tunn...
